متن کاملHořava-Witten Stability: eppur si muove
We construct exact time-dependent solutions of the supergravity equations of motion in which two initially non-singular branes, one with positive and the other with negative tension, move together and annihilate each other in an all-enveloping spacetime singularity. Among our solutions are the Hořava-Witten solution of heterotic M-theory and a Randall-Sundrum I type solution, both of which are ...
